I’m not that sure about my answer, but if I’m not wrong:
Total cost with 6 snacks: 78$
Total cost with x snacks: anything above 60$
Well 7+5= 12. 12/6=6. 6+10=16. 16 by the power of two is 256
<span>40x/64ydivided by 5x/8y would be better written as
</span><span>40x/64y
------------ which in turn would be clearer if written as
</span><span>5x/8y
40x
--------
64y
==========
5x
------
8y
Now invert (5x/8y) and multiply (40x/64y) by your result:
</span> 40x 8 y
-------- * ------ Reducing, we get 8/8, or 1. The answer is 1.
64y 5x
V= πr^2h
This is the formula for volume of a cylinder. The volume formula builds off the area formula. Where area is more 2-dimensional, volume is 3-dimensional. You can think of a flat sheet of paper for area (2-dimensional) and a solid box for volume (3-dimensional).
Usually your teacher would give the formulas when starting this section of math. From there, either keep a list of needed formulas in your math folder for easy reference, or try to memorize the formulas for the current section of math you are working on. Some teachers allow formula reference sheets and some do not.
Hope this answers your question! :)
